17 Bad Skin Habits

The skin sins to leave behind.

SKIPPING BROAD-SPECTRUM SUNSCREEN

The best way to keep your skin from getting wrinkled, saggy, and speckled is sunscreen, SPF 30 at the minimum. Broad-spectrum formulas (meaning they shield against both UVA and UVB rays) with Mexoryl or Helioplex offer the longest-lasting protection. (We like Neutrogena Ultra Sheer Dry-Touch Sunblock SPF 55 and La Roche-Posay Anthelios 40.) Apply a whole tablespoon to your face, and the equivalent of a shot glass on your body. For workdays, reapply before your commute home if the sun is still out—even if you'll be in a car. And for days when you'll be outside for an extended period of time, reapply every two hours. We know it's a pain, but come on—you'll get the last laugh instead of the first laugh lines.
